Discrepancies in Race and Ethnicity Documentation: a Potential Barrier in Identifying Racial and Ethnic Disparities

Abstract

BackgroundData collection on race and ethnicity is critical in the assessment of racial disparities related to health. Studies comparing clinical and administrative data show discrepancies in race documentation and attribution.MethodsSelf-reported data from two studies were compared to demographics in the electronic health record (EHR) extracted from the Biomedical Translational Research Information System (BTRIS) repository. McNemar and Bhapkar analyses were conducted to quantify the agreement of ethnicity and race between self-reported and EHR data. Pearson’s chi-square tests were used to explore the relationship between acculturation, length of time in the USA, country of residence, and how individuals self-reported their race.ResultsThe sample (n = 280) was predominantly female (52.1 %), with a mean age of 47 (SD ± 13.74), mean years in the USA were 12.8 (SD ± 11.67) and the majority were born outside of the USA. (55.6 %). Those who self-identified as Hispanic (n = 208) scored a mean of 5.5 (SD ± 3.07) on the short acculturation scale (SAS) that ranges 4 to 20; lower scores indicate less acculturation. A significant difference was found between the way race is reported in the electronic medical record and self-reported data among those people who identified as Hispanic, with significant differences in the white (p < 0.0001) and other (p < 0.0001) categories.ConclusionsThe misclassification of race is most frequent in those individuals who self-identified as Hispanic. As the Hispanic population in the USA continues to grow, understanding the factors that affect the way that individuals from this heterogeneous population self-report race may provide important guidance in tailoring care to address health disparities.

Standardized Biogeographic Grouping System for Annotating Populations in Pharmacogenetic Research

“…This approach highlights the importance of understanding and recording detailed self‐identified and self‐reported race and ethnicity in the context of genetic studies. Although self‐reported race and ethnicity can be influenced by an individual's social and cultural background and, thus, may not perfectly correlate with genetic ancestry, it is more reliable than assignment of race or ethnicity by another person (e.g., a healthcare professional) . However, it should be noted that self‐reported measures can be complicated by collection processes, including an incomplete selection of possible identity categories or allowing only one selection and thus failing to capture whether an individual may identify with multiple categories or none at all .…”

The quality of social determinants data in the electronic health record: a systematic review

“…information is often abstracted directly from medical records. 10 Also included were several large databases compiled from electronic health record EHR data, such as the Biomedical Translational Research Information System repository, 11 and the Healthcare Cost and Utilization Project’s State Inpatient Database. 4 , 12–14 Research using datasets from large cohort studies such as the National Birth Defect Prevention Study were included if the study’s dataset was drawn directly from the participant’s medical records.…”

COVID-19 health inequities and association with mechanical ventilation and prolonged length of stay at an urban safety-net health system in Chicago

“…Similar to other findings in urban populations, our study found that non-Hispanic Black and Hispanic patients have a statistically significantly higher odds of positivity (1.5 and 2.5 respectively) [ 20 – 22 ]. Evidence suggests that Hispanic ethnicity is often underreported in healthcare settings, therefore even with our surname recode methodology described above, it is possible this is an underestimate of the impact on the Hispanic community [ 23 ]. Some of these disparities can be explained by the long-term disinvestment in these communities which lead to high rates of poverty, poor access to quality healthcare, and distrust of the medical community [ 24 , 25 ].…”
